Amy then changed into a scruffy-looking white top and a pair of denim shorts and hot-footed it with her new husband to the Big Pink Diner in Miami for their celebratory 'slap-up' meal.

It is the same restaurant Tony Blair used while staying at Bee Gee Robin Gibb's beach mansion.

Arriving back at Miami's Shore Club Hotel separately, the couple refused to talk to reporters, but Amy winked when asked if she was married. Blake, 24, said: "We had a good day but I can't really talk about it."

They have reportedly signed a £250,000 magazine deal.

Blake's father Giles, who lives in Newark, Nottinghamshire, said: "I spoke to them and they are very happy. We will support him and Amy in whatever they decide to do."

He said they would 'wait and see' if the couple would have a more public ceremony when they returned from the United States.

Marriage clerk Sammy Calixte confirmed the ceremony had taken place, saying: "They came in to get married and they were alone. I read the vows and each one said "I do".

"When I pronounced them man and wife, they hugged and kissed." The newlyweds - who met two years ago - then had a photoshoot at the hotel before heading out, only to be caught in a tropical downpour.

Blake has altered his MySpace website to change his status from single to married.
